Here, experimental and numerical studies on the gas explosion hazards of container type lithium-ion battery energy storage station are carried out. In the experiment, the LiFePO 4 battery module of 8.8kWh was overcharged to thermal runaway in a real energy storage container, and the combustible gases were ignited to trigger an explosion.
It can be seen that in the early stage of the explosion, due to the existence of battery containers on both sides, the flame spread to the surrounding unburned area in a form of cylinder. Moreover, it can be seen from YZ profile that the upward development of combustion rate was more prominent.
Starting from the external strain mechanism of the lithium battery, the strain change of the lithium battery explosion proof valve under normal conditions and overcharge is studied. Based on the comparison of the two conditions, an online warning scheme using sliding window and data standard deviation is proposed.
Therefore, the safety protection and explosion suppression ability of lithium-ion battery ESS are significantly important. It is urgent to conduct in-depth studies on the gas explosion behavior and characteristics of lithium-ion battery ESS.
Zhao et al. carried out a series of thermal explosion experiments of 18650 lithium-ion batteries under different states of charge (SOCs) in hermetic space, and the experimental results showed that the risk of explosion upgrading with the increase of SOC.
Considering that gas explosion may cause thermal runaway of battery module in the actual scene, the existence of high-temperature zone may be longer and the temperature peak may be higher. After the combustible gas got on fire, the gases volume expanded by high-temperature compresses the volume of the surrounding gases.
